DEVICE FOR IMPRESSING SEALS ON PAPERS.

To all whom it may concern:

Be it known that I, FELIX Gro'rTsoHALk, a citizen of the United Statesof America, and ay resident of New York, in the county of New York andState of New York, have invented certain new and useful Improvements inDevices for Impressing Seals on Papers, of which the following is afull, clear, and exact description.

The object of this invention is to provide in a device for impressingseals on papers, companion registering dies which are detachably engagedand carried by opposed supports therefor, one of which is movable towardthe other, and has means for operating it, so that the sealing dies mayat pleasure be removed and replaced by other dies' like them in allrespects excepting as to the characters or inscriptions thereon, asecondary object being to provide constructions which insure absoluteand invariable registry of the dies, which are susceptible, mostcheaply, of practicable and accurate manufacture, and which permit ofthe most quick and convenient detachment of the dies-from their carryingsupports and the replacement of interchanged dies as occasion may renderdesirable.

The invention consists in the combination or arrangement of parts andthe construction of certain of the parts substantially as hereinafterdescribed in conjunction with the accompanying drawings and set forth inthe claim.

In the drawings z-Figure l is a side elevation of a seal impressingdevice in which the present improvements are embodied; Fig. :2 is across sectional view on a larger scale as taken on line 2 2, Fig. l;Fig. 8 is a horizontal section as taken on line 3-3, Fig. 2; Fig. 4 is afront elevation of the lower portion of Fig. 8.

Similar characters of reference indicate corresponding parts in all ofthe views.

In the drawings,-A and B represent opposed supports for plates C, and D,which comprise companion sealing dies c and d,- these supports in thepresent showing being comprised as appurtenances of die carriers, F, forthe upper one (the lower one being represented by B already employed)which are horizontally movable in a supporting and guiding frame, andwhich have adjusting means therefor comprising the feed screws f f andmeans (not fully shown) for operating them substantially as disclosed inSpecification of Letters Patent.

Application filed November 18, 1908.

Patented Nov. 2, 1,909. serial No. 463,244.

Letters Patent of the United States granted to me May 26, 1908, No.888,997. The upper one C of the opposed die supports is carried at thelower end of stem g which has a reciprocating movement through thesupport E andis operated by the lever H. The said supports C and D have,each, opposite parallel portions h which are extended slightly rightangularly beyond their-plane faces and which are provided with theinwardly opening grooves iz' (one boundary of each groove beingpracticably constituted by a gib y' screwed in place).

The plates which comprise the companion registering dies have thinparallel straight edge flanges m m which slidably engage in the groovesi; and the die plates have their sliding movements in said grooves totheir registering positions limited by the stop pins n and o, the formerdepending slightly below the support C near its rear edge while the oneo projects upwardly beyond the horizontal top face of the support B.Said die plates C and D have within their faces which adjoin thesupports on which they are mounted shallow circular depressions [ff-Fig.2,-within which the protruding extremities of spring pressed plungers u,which are carried by the supports A and B have snap catch engagements,and are operative, as detents, to reliably retain the die plates withwhich the sealing machine is equipped in their registering positions.

The plungers are shown as having plunger heads playing in sockets otherefor which are provided in the die supports or carriera-stems i0projecting axially beyond the plunger head through reduced openings incontinuation of the ends of the socket and having limiting stops orshoulders while between the end walls of the sockets and the plungerheads are accommodated spiral springs y in compression and encirclingthe plunger stems.

So soon as the die plates on being slid to place (at which time thespring plungers, the rounded ends of which protrude normally, but areforced to retracted positions) come to their limitationsA against thestops therefor the die plate depressions are centrally alined with theplungers which are spring pressed into engagement therein.

Intelligently applied pressure edgewise against the die plates from therear will be effective to displace them from their supports, theinclinations of the depressions acting, cam-like, to crowd the plungersfrom their engagement, and new or different die plates may be mosteasily and instantaneously placed in their registering positions inengagement with the supports A and B.

In a device of the character described, opposed supports, one of whichis movable toward the other and having means for operating it, saidsupports having opposite parallel portions provided with inwardlyopening grooves having limiting stops at their rear parts and havingspring pressed plungers located between their oppositely groovedportions and protruding in approached relations beyond the faces of theY supports, the plates Comprising companion dies edgewise slidablyengaged in said groove portions of the supports and positioned inregistry by said stops and having depres-r sions, Within their faces,Which adjoin the supports, Within which the protruding eX- tremities ofthe plungers have snap catch engagements.
